Nanoengineering of optical semiconductors is today used to make DVDlasers, LEDs, sensors, components for optical fibre communications (broadband), such as detectors, modulators, lasers and high-speed electronics, and much more.

At DTU Fotonik we are experts on designing and modeling semiconductor optical devices, and in the DANCHIP cleanroom we tranform our ideas into reality. World class test laboratories are also available. Please see our education pages if you want to participate in the work as a student.

 

The nanophotonic devices group has a number of current research topics listed below. Click on heading to find out more.

 

Mode-locked lasers

Mode-locked lasers are pulsed lasers where pulses of light are circulating in the laser cavity. We have activities on both all semiconductor lasers and filters for fiber lasers.

 

Photonic crystals devices 

Modern process technology allows devices with high refractive index contrast patterned on a submicron scale to control light. An popular subclass of this field is called photonic crystals and we design, fabricate and measure on devices employing such structures.

 

VCSELs

We design and realise vertical-cavity surface-emitting lasers for applications in sensing and medical imaging.

 

X-ray detector

The project, in collaboration with Risø, has as final objective the fabrication and characterisation of an InP x-ray detector with a spatial resolution of 100nm or below.

 

Quantum dots

We grow and characterize quantum dots on InP materials.

 

Technology

Semiconductor technology is an important part of realizing functional nanophotonic devices.
